    Speed, RPM and SYNC

    Last post for today. There was another thread that mentioned expected top speed and associated RPM. The other day I took a picture when running near full throttle simply because it felt so good to have nearly 100% of the speed designed into the boat while the RPM / motors were in Sync...

    2000 SeaDoo GTX Milenium Edition

    Hey i was just wondering what other people with a 2000 SeaDoo GTX Milenium Edition with a stock engine got for their top speed. My speedometer showed 68 on a speed run but later i did a GPS recording and it showed 51 as the top speed and i couldn't believe that the speedometer was so far off.
